Shortening probes Rod and rope probes can be easily shortened. This is necessary if the distance to the container floor or outlet cone is less than 150 mm in the case of a rope probe, or less than 100 mm in the case of a rod probe or less than 50 mm in the case of a coax probe. Shortening rod probes The rods of a rod probe are shortened by sawing or separating at the bottom end. M4 secured with Loctite 243 torque 4 mm cable = 5 Nm 6 mm cable =15 Nm 60 / 80 mm Shortening rope probes • Remove ballast weight: – The weight is fixed to the probe rope with 3 Allen setscrews (M4, Allen key AF3). The screws are secured with Loctite. This may first have to be made plastic with a hot air apparatus. • Remove released rope from the weight • Measure off new rope length • Wrap adhesive tape around the rope at the point to be shortened to prevent it from fanning out. • Saw off the rope at a right angle or cut it off with a bolt cutter. • Insert the rope completely into the weight, – thin rope (4 mm) 60 mm deep, – thick rope(6 mm) 80 mm deep The weight is then refixed to the rope: • Reapply screw locking fluid (we recommend Loctite type 243) to the setscrews and screw into place. • When doing so, observe the following torques: – For 6 mm rope: 15 Nm – For 4 mm rope: 5 Nm Shortening coax probes Coax probes can be shortened max. 80 mm from the end. They have centering units inside which fix the rod centrally in the pipe. The centerings are held with borders on the rod. Shortening is possible up to approx. 10 mm below the centering. Endress+Hauser 13 3 Mounting Levelflex M FMP 40 with HART/4...20 mA 3.4.2 Engineering hints for level measurement in bulk solids and fluids The following installation instructions apply for rope and rod probes for measurement in bulk solids and fluids. Coax probes are suitable purely for measurement in fluids. They function practically independent of all installation conditions and can, therefore, be installed as desired. • Temperature conditions must be met (see page 81). • It is recommended that a protective cover (1) is used, in order to protect the transmitter against direct sunlight or rain (see »Accessories« on page 67.). Mounting location • Do not mount rod or rope probes in the filling curtain (3) • Mount rod and rope probes away from the wall (B) at such a distance that, in the event of build-up on the wall, there is still a minimum distance of 100 mm between the probe and the build-up. • Mount rod and rope probes as far away as possible from installed fittings. "Mapping " must be carried out during commissioning in the event of distances < 300 mm. • When installing rod and rope probes in plastic containers, the minimum distance of 300 mm also applies to metallic parts outside the container. • Rod and rope probes may not, at times, contact metallic container walls or floors. • In metal containers, do not install rod and rope probes exactly in the centre (2). • Minimum distance of probe end to the container floor (C): – Rope probe: 150 mm – Rod probe: 100 mm – Coax probe: 50 mm • When installing outdoors, it is recommended that you use a protective cover (1) see »Accessories« on page 67.. 14 1 2 3 B C Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3 Mounting Other installations • Select the mounting location such that the distance to internals (5) (e.g. limit switch, struts) > is 300 mm over the entire length of the probe, also during operation. • Probe must within the measuring span not touch any internals during operation. If necessary: when using rope probes the probe end (4) may be fixed to ensure that (see page 23)!. 5 Optimization options • Interference echo suppression: Measurement can be optimised by electronically tuning out interference echoes. 4 Minimum distance B of the probe to the container wall: Wall min. distance B Metal 100 mm for smooth walls Plastic 100 mm, min. 300 mm to metallic components outside of the tank Concrete 0.5 m/20", otherwise the max. possible measuring range is reduced Distance to protruding internals min. 300 mm. Endress+Hauser 15 3 Mounting Levelflex M FMP 40 with HART/4...20 mA Standard installation • Probes are mounted to the process connection with threaded connections or flanges and are usually also secured with these. If during this installation there is the danger that the probe end moves so much that it touches the tank floor or cone at times, the probe must, if necessary, be shortened and fixed down. The easiest way to fix the rope probes is to screw them to the internal thread on the lower end of the weight. Thread size, see page 23. • The ideal installation is mounting in a screwed joint / screw-in sleeve which is internally flush with the container ceiling. • If installation takes place in a nozzle, the nozzle should be 50 ... 150 mm in diameter and should not be more than 150 mm high. Installation adapters are available for other dimensions, see »Accessories« on page 67. installation with welding boss 1½" or ¾" installation in nozzle ≤ 150 mm (≤ 4") diameter nozzle: ≤ DN150 (≤ 6”) Probe length • The measuring range is directly dependent on the probe length. If the probe is not fixed at the bottom end, the following distances to the container floor must be observed: – Rope probe: 150 mm – Rod probe: 100 mm – Coax probe: 30 mm It is better to order probes too long than too short since it is possible to shorten the probe if necessary. 16 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3.4.3 3 Mounting Special notes for bulk solids • In the case of bulk solids, as great a distance as possible from the filling curtain is especially important to avoid wear. • In concrete silos, a large distance (B) should be observed between the probe and the concrete wall, if possible >= 1m, but at least 0.5m B Installation in concrete silos Installation, for example, into a thick concrete ceiling should be made flush with the lower edge. Alternatively, the probe can also be installed into a pipe that must not protrude over the lower edge of the silo ceiling. Installation suggestions see diagram. ≥ 100 mm ≥ 100 mm metal Ø 80...150 mm Extension rod / Centering (see accessories) Endress+Hauser 17 3 Mounting Levelflex M FMP 40 with HART/4...20 mA 3.4.4 Installation in bulk solid silos Tensile load Bulk solids exert tensile forces on rope probes whose height increases with:: • the length of the probe, i.e. max. cover, • the bulk density of the product, • the silo diameter and • the diameter of the probe rope The following diagrams show typical loads for frequently occurring bulk solids as reference values. The calculation is performed for the following conditions: • Suspended probe (probe end not fixed at the bottom) • Free-flowing bulk solid, i.e. mass flow. A calculation for core flow is not possible. In the event of collapsing cornices, considerably higher loads can occur. • The specification for tensile forces contains the safety factor 2, which compensates for the normal fluctuation range in pourable bulk solids. 18 35 16 30 40 25 20 30 15 20 10 12 polyethylene pellets smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m 14 pulling force, 6 mm rope [kN] 11 10 9 8 12 7 10 6 8 5 4 6 3 4 10 2 5 0 0 5 10 15 20 25 30 2 0 35 1 0 0 5 10 level [m] 60 24 25 30 0 35 50 20 16 14 20 12 15 10 8 10 6 4 5 pulling force, 6 mm rope [kN] 18 25 40 cement smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m 22 pulling force, 4 mm rope [kN] pulling force, 6 mm rope [kN] 30 20 level [m] wheat smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m 35 15 35 30 40 25 20 30 15 20 10 pulling force, 4 mm rope [kN] pulling force, 6 mm rope [kN] 50 40 pulling force, 4 mm rope [kN] silica sand smooth metallic walls silo diameter 12 m silo diameter 9 m silo diameter 6 m silo diameter 3 m pulling force, 4 mm rope [kN] 60 10 5 2 0 0 5 10 15 20 level [m] 18 25 30 0 35 0 0 5 10 15 20 25 30 0 35 level [m] Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3 Mounting Since the tensile forces are also heavily dependent on the viscosity of the product, a higher safety factor is necessary for highly viscous products and if there is a risk of cornice build-up. In critical cases it is better to use a 6 mm rope instead of a 4 mm one. The same forces also act on the silo cover. On a fixed rope, the tensile forces are definitely greater, but this can not be calculated. Observe the tensile strength of the probes or ensure that the tensile strength of the probes is not exceeded. Options for reducing the tensile forces: • Shorten the probe • If the maximum tensile load is exceeded, check whether it would be possible to use a non-contact ultrasonic device. Endress+Hauser 19 3 Mounting Levelflex M FMP 40 with HART/4...20 mA 3.4.5 Installation in liquids tanks • When installing in agitation units, check whether a no-contact process (ultrasonic or radar) would be better suited, especially if the agitator generates large mechanical loads on the probe. • If Levelflex is, nevertheless, installed in tanks with agitators, it is better to use coax probes which have a greater lateral loading capacity. Standard installation Using a coax probe offers great advantages when the viscosity of the product is < 500 cst and it is certain that the product does not accumulate build-up: • Greater reliability: As of dielectric constant=1.4, measurement functions independently of all electrical properties in all liquids. • Internals in the tank and nozzle dimensions do not have any influence on measurement. • Higher lateral load-bearing capacity than rod probes. • For higher viscosity a rod probe is recommended, or using a non-contact measuring principle. Installation in horizontal cylindrical and standing tanks • Use a coax or rod probe for measuring ranges up to 4 m. For anything over this or if there is too free cover space use a 4 mm rope probe. • Installation and possible fixing as with bulk solids. • Any distance from wall, as long as occasional contact is prevented. • Do not mount a rod or rope probe (1) exactly central when using metallic containers. Central mounting doesn‘t impair coax probe (2) performance. • When installing in tanks with a lot of internals or internals situated close to the probe: Use a coax probe. 20 1 2 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3 Mounting Installation in underground tanks • Use coax probe for nozzles with large diameters in order to avoid reflections at the nozzle wall. Measurement in corrosive fluids For measurement in corrosive liquids, it is possible to install a rod probe in a closed plastic pipe with a diameter of up to approx. 50 mm. When using plastic tanks it is also possible to mount the probe on the outside of the tank (see Installation instructions on page 24). Levelflex measures the level through the plastic in both cases. Installation in stilling well or bypass • A rod probe can be used for pipe diameters up to 150 mm, for diameters above that the flange with horn adapter recommended. • When installing a rod probe into a metallic pipe with internal diameter of up to 150 mm, you have all the advantages of a coax probe. • Welded joints that protrude up to approx. 5 mm/0.2" inwards do not influence measurement. Endress+Hauser 21 3 Mounting Levelflex M FMP 40 with HART/4...20 mA Mounting Location • Recommended distance B wallmounted rope probe: ~1/6...1/4 of the container diameter (min. 100 mm/4", concrete silos: min. 500 mm). • Not central (2) in metallic tanks. • Not in the filling curtain (3). • Please order the probe length such that it ends approx 30 mm above the floor of the tank. • Temperature conditions must be met. • It is recommended that a protective cover (1) be used, in order to protect the transmitter against direct sunlight or rain. Mounting and demounting are carried out simply with a clamp (see »Accessories« on page 67.). 1 2 3 B Tank installations • Select the mounting location such that the distance to internals (4) (e.g. limit switch, struts) is > 300 mm. Optimization options • Interference echo suppression: Measurement can be optimised by electronically tuning out interference echoes. • Bypass pipe and stilling well (only for liquids): for viscosities of up to 500 cst, a bypass pipe, stilling well or a coax probe can be used to prevent interference. 22 4 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3.4.6 3 Mounting Notes on special installation situations Fixing rope probe • The end of the probe needs to be secured if the probe would otherwise touch the silo wall, the cone or another part, or the probe comes closer than 0.5 m to a concrete wall. This is what the internal thread in the probe weight is intended for: – for 4 mm rope:M14 – for 6 mm rope:M20 • Preferably use the 6 mm rope probe due to the higher tensile strength when fixing a rope probe • The fixing must be either reliably grounded or reliably insulated (see accessories). If it is not possible to mount the probe weight with a safe earthed connection, it can be secured using an isolated eyelet, which is available as an accessory (see page 69). • In order to prevent an extremely high tensile load and the risk of rope crack, the rope has to be slack. Make the rope longer than the required measuring range such that there is a sag in the middle of the rope that is ≥ 1cm/m (1"/ 100") of the rope length. Reliable, earthed mounting sag of the rope: ≥1cm/m of the rope length Reliable, isolated mounting Mounting-kit isolated (see accessories) Mounting and contact with a bolt 4mm-rope: M14 6mm-rope: M20 Endress+Hauser 23 3 Mounting Levelflex M FMP 40 with HART/4...20 mA Installation from the side • If installation from above is not possible, the Levelflex can also be mounted from the side. • In this case, always fix the rope probe (see »Fixing rope probe« ). • Support coax probe if the lateral loadbearing capacity is exceeded. Only fix rod probes at the probe end. • Connect rod probe metallically with the container wall. Installation in plastic containers Please note that for rod and rope probes only with a metallic surface at the process connection an optimal performance can be guaranteed. When installing the probe in plastic silos, whose silo cover is also made of plastic or silos with wood cover, the probes must either be mounted in a ≥ DN50 / 2" metallic flange, or a metal sheet with diameter of ≥ 200 mm must be mounted under the screw-in piece. metal sheet or metal flange silo roof of plastic or wood metal sheet or metal flange max. 20 mm Wall thickness for GFK/PP < 15 mm • It is also possible to mount the probe externally on the tank wall for measuring in Aqueous solutions. Measurement then takes place through the tank wall without contacting the medium. If people are in the vicinity of the probe mounting location, a plastic half pipe with a diameter of approx. 200 mm, or some other protective unit, must be affixed externally to the probe to prevent any influences on the measurement. • There must not be any metallic reinforcement rings secured to the tank. • The wall thickness should be at Fibre-Glass Reinforced Plastic/PP < 15 mm. • There must be no open space between the tank wall and the probe. 24 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 3 Mounting • If measuring externally, an automatic probe length determination and a two point linearisation must be performed in order to compensate for the time-of-flight change caused by the plastic wall. Installation in nozzles > 150 mm high If, when installing probes in nozzles DN 40...250/1 ½"...10" with nozzle height (HS) of > 150 mm/6", the probe could touch the lower edge of the nozzle due to moving materials in the container, we recommend using an extension rod with or without centering disk. This accessory consists of the extension rod corresponding to the nozzle height, on which a centering disk is also mounted if the nozzles are narrow or when working in bulk solids. This component is delivered separately from the device. Please order the probe length correspondingly shorter. For the exact length of the rod see page 68. Order codes for specific nozzle nominal diameters and heights can be found on page 68. Only use centering disks with small diameters (DN 40 and DN 50) if there is no significant build-up in the nozzle above the disk.

Installation in DN 200/DN 8" and DN 250/DN 10"nozzles When installing the Levelflex in nozzles of > 210 mm / 8", signals are generated by reflections on the nozzle wall, which can sometimes lead to faulty measurements in the case of products with small dielectric constants With nozzle diameters of 200 mm / 8" or 250 mm / 10", therefore, a special flange with a “horn adaptor” must be fitted. Nozzles with nominal diameters greater than DN 250 / 10" should be avoided. 204 mm DN200 (8") DN250 (10") Endress+Hauser 25 3 Mounting Levelflex M FMP 40 with HART/4...20 mA Installation in > DN 300/DN 12" nozzles If installation in > 300mm/12" nozzles is unavoidable, installation must be carried out in accordance with the sketch on the right. pipe Ø 150 … 180 Approx. flush with the lower edge of the nozzle (± 50 mm). 3.4.7 plate nozzle diameter plate diameter DN 300 280 > DN 400 > 350 Installation for difficult to access process connections For tight spaces or temperatures above that in the graphic, the electronics housing can be ordered with distance pipe or connecting cable (seperate housing). 400 Installation with distance pipe • Follow installation instructions on Page 14 ff.. • After mounting, the housing can be turned 350°, in order make access to the display and the connection compartment easier. • The max. measuring range is reduced to 34 m/1338".

If two or more system or process errors occur, the error with the highest priority is the one shown on the display. The measuring system distinguishes between two types of error: • A (Alarm): Instrument goes into a defined state (e.g. MAX 22 mA) Indicated by a constant symbol. (For a description of the codes, see Table 9.2 on Page 72) • W (Warning): Instrument continue measuring, error message is displayed. Indicated by a flashing symbol. (For a description of the codes, see Table 9.2 on Page 72) • E (Alarm / Warning): Configurable (e.g. loss of echo, level within the safety distance) Indicated by a constant/flashing symbol. (For a description of the codes, see Table 9.2 on Page 72) ⇒ Error messages Error messages appear as four lines of plain text on the display. In addition, a unique error code is also output. A description of the error codes is given on Page 72. • The "diagnostics (0A)" function group can display current errors as well as the last errors that occurred. • If several current errors occur, use O or S to page through the error messages. • The last occurring error can be deleted in the "diagnostics (0A)" function group with the function"clear last error" (0A2). 42 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 5.5 5 Operation HART communication Apart from local operation, you can also parameterise the measuring instrument and view measured values by means of a HART protocol.

Note! The Levelflex M allows to check for broken probe. On delivery, this function is switched off, because otherwise shortening of the probe would be mistaken for a broken probe. If you want to check the probe for a crack select the "broken probe det" (019) function in the "safety settings" (01) function group. Complex measuring operations necessitate additional functions that the user can use to customise the Levelflex as necessary to suit his specific requirements. The functions available to do this are described in detail in the BA 245F. Comply with the following instructions when configuring the functions in the "basic setup" (00): • Select the functions as described on Page 35. • Certain functions (e.g. starting an interference echo mapping (053)) prompt you to confirm your data entries. Press O or S to select "YES" and press F to confirm. The function is now started. • If you do not press a key during a configurable time period (→ function group "display (09)"), an automatic return is made to the home position (measured value display). 48 ! Note! • The instrument continues to measure while data entry is in progress, i.e. the current measured values are output via the signal outputs in the normal way. • If the envelope curve mode is active on the display, the measured values are updated in a slower cycle time. Thus, it is advisable to leave the envelope curve mode after the measuring point has been optimised. • If the power supply fails, all preset and parameterised values remain safely stored in the EEPROM. " Caution! All functions are described in detail, as is the overview of the operating menu itself, in the manual “Description of the instrument functions – BA 245F”, which is a separate part of this operating manual.

The number of digits after decimal point can be selected in the "no.of decimals" (095) function. 6.4.1 Function group "basic setup" (00) ⇒ Function "tank properties" (002) ⇒ This function is used to select the tank properties. Selection: • standard • aluminium tank • plastic tank • bypass / pipe • coax probe • concrete wall standard The "standard" option is recommended for normal containers for rod and rope probes. aluminium tank The "aluminium tank" option is designed especially for high aluminium silos that cause an increased level of noise when empty. This option is only useful for probes longer than (< 4 m). For short probes (< 4 m) select the "standard" option. ! Note! If "aluminium tank" is selected, the device calibrates of its own accord when first filled, depending on the medium's properties. Slope errors can, therefore, occur when beginning the first filling procedure. plastic tank Select the "plastic tank" option when installing probes in wood or plastic containers without metallic surfaces at the process connection (see installation in plastic containers). When using a metallic surface at the process connection, the "standard" option is sufficient. ! Endress+Hauser Note! In principle the employment of a metallic surface area should be preferred at the process connection! 49 6 Commissioning Levelflex M FMP 40 with HART/4...20 mA bypass / pipe The "bypass / pipe" option is designed especially for the installation of probes in a bypass or a stilling well. coax probe Select the "coax probe" option when using a coaxial probe. When this setting is made, the evaluation is adapted to the high sensitivity of the coax probe. This option should, therefore, not be selected when using rope or rod probes. concrete wall The "concrete wall" option takes into account the signal-damping property of concrete walls when mounting with < 1 m distance to the wall.

Pay special attention to the gasket grooves and crevices where fluid may be present. This is especially important if the fluid is dangerous to health, e.g. corrosive, poisonous, carcinogenic, radioactive, etc. • Always enclose a duly completed "Declaration of contamination" form (a copy of the “Declaration of contamination” is included at the end of this operating manual). Only then can Endress +Hauser transport, examine and repair a returned device. • Enclose special handling instructions if necessary, for example a safety data sheet as per EN 91/155/EEC. Additionally specify: • An exact description of the application. • The chemical and physical characteristics of the product. • A short description of the error that occurred (specify error code if possible) • If necessary, give the error code. 9.6 Disposal In case of disposal please seperate the different components according to their material consistence. 9.7 Software history Software version / Date Software changes V 01.02.00 / 04.2002 Original software.

Endress+Hauser 79 10 Technical data Levelflex M FMP 40 with HART/4...20 mA 10 Technical data 10.1 Technical data at a glance Application Application The Levelflex M performs continuous level measurement of powdery to granular bulk solids and liquids e.g. plastic granulate. Probes are available with threaded process connections from ¾" and flanges from DN40 / 1½": • Rope probes, above all for measurement in bulk solids, measuring range up to 35 m/1378" • Rod probes, above all for liquids • Coax probes, for liquids Function and system design Measuring principle The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device see page 12) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. This method is also known as TDR (Time Domain Reflectometry). Equipment architecture see Page 91 ff. Input Measured variable The measured variable is the distance between the reference point and the product surface. Subject to the input zero point empty distance the level is calculated. Alternatively, the level can be converted by means of linearisation into other variables (volume, mass). Measuring range see Technical Information TI 358F Output Output signal • 4…20 mA with HART protocol Signal on alarm Error information can be accessed via the following interfaces: • Local display: – Error symbol (see page 38) – Plain text display • Current output • Digital interface Auxiliary energy 80 Electrical connection Two housings are available: • Housing F 12 with additionally sealed terminal compartment for standard or EEx ia • Housing T 12 with separate terminal compartment for standard, EEx e or EEx d..

A detailed description of the function groups, functions and parameters is given in the documentation BA 245F/00/en - a description of the instrument functions of the Levelflex M. 87 11 Appendix Levelflex M FMP 40 with HART/4...20 mA 11.4 Function and system design 11.4.1 Measuring principle The Levelflex is a "downward-looking" measuring system that functions according to the ToF method (ToF = Time of Flight). The distance from the reference point (process connection of the measuring device see page 12) to the product surface is measured. High-frequency pulses are injected to a probe and led along the probe. The pulses are reflected by the product surface, received by the electronic evaluation unit and converted into level information. This method is also known as TDR (Time Domain Reflectometry). flange: reference point of measurement 20 mA 100% D E probe length LN F L 4 mA 0% Input The reflected pulses are transmitted from the probe to the electronics. There, a microprocessor analyses the signals and identifies the level echo, which was generated by the reflection of the high-frequency pulses at the product surface. This clear signal finding benefits from the many years experience with pulse time-of-flight procedures that have been integrated into the development of the PulseMaster® Software. The distance D to the product surface is proportional to the time of flight t of the impulse: D = c · t/2, with c being the speed of light. Based on the known empty distance E, the level L is calculated: L=E–D Reference point for "E" see above diagram, Details see page 47. The Levelflex possesses functions for the interference echo suppression that can be activated by the user. They guarantee that interference echoes from e.g. internals and struts are not interpreted as level echoes. 88 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 11 Appendix Output The Levelflex is initially adjusted at the factory to the probe length ordered, so that in most cases only the application parameters, that automatically adapt the device to the measuring conditions, need to be entered. For models with current output, the factory adjustment for zero point and span is F 4 mA and 20 mA, for digital outputs and the display module 0 % and 100 %. A linearisation function with max. 32 points, that is based on a manually or semiautomatically input table, can be activated on-site or via remote operation. This function enables, for example, the conversion of the level into units of volume or weight. An evaluation of the measurement with the aid of the envelope curve Typical curve shape The following examples display typical curve shapes for a rope or rod probe in an empty tank. For all probe types, a negative probe end signal is shown. For rope probes, the end weight causes an additional preliminary positive echo (see rope probe diagram). Probe end signal Launch pulse Probe end signal Launch pulse Rod probe Rope probe Level echoes are detected as positive signals in the envelope curve. Interference echoes can be both positive (e.g. reflections from internals) and negative (e.g. nozzles). The envelope curve, the map and the differential curve are used for the evaluation. Level echoes are searched for in the differential curve. Endress+Hauser 89 11 Appendix Levelflex M FMP 40 with HART/4...20 mA Evaluation of the measurement: • The map must correspond to the course of the envelope curve (for rod probes up to approx. 5 cm and for rope probes up to approx. 25 cm before the end of the probe) when the tank is empty. • Amplitudes in the differential curve should be at a level of 0 mV when the tank is empty and lie within the span that is specified by the probe-specific blocking distances. In order to not detect any interference echoes, there must be no signals that exceed the echo threshold when the tank is empty. • For partially-filled tanks, the map may only differ from the envelope curve at the position of the level echo. The level signal is then detected unequivocally as a positive signal in the differential curve. For detecting the level echo, the amplitude must lie above the echo threshold. Negative probe end signal Launch pulse Envelope curve Mapping Differential curve = Envelope curve Mapping 90 Endress+Hauser Levelflex M FMP 40 with HART/4...20 mA 11 Appendix 11.4.2 Equipment architecture Stand-alone • Power supply directly from power line (4-wire) or from transmitter power supply unit (2-wire). • Operation by on-site display or remote operation via HART protocol.
